Bronchoscopic delivery of aminocaproic acid as a treatment for pulmonary bleeding: A case series.

Objective: Bronchoscopy is an essential therapeutic modality in the treatment of pulmonary bleeding. Although numerous endoscopic treatments exist, topical ε-aminocaproic acid has not been described in the literature. This study documents the use of this novel treatment for pulmonary bleeding and compares it to available evidence for tranexamic acid, a similar anti-fibrinolytic agent.
